@lsl7994: Good to know that the port also works for 101b, if possible please post here if optical zomming during video and AF-scan during video is also working.
Regarding the battery stuff: Every battery/camera combination looks to be different. Even if the battery stated as 3,7V battery, the measured voltage for my battery is (fully charged) almost 4,1V. But it is possible to set the MIN/MAX value via OSD (OSD-Parameters->Battery->Battery MIN/MAX Voltage)
